Antweight robots are one of the smallest classes of combat robots to emerge from the popular "Robot Wars" TV show.

The basic build rules are that they must fit into a 4" (10cm) cube, and they are limited to a weight of 150g (walkers are allowed an extra 75g).

They are radio-controlled and fight on a 2'6" (76cm) square platform in a fully enclosed arena. Competitions are full combat, you win by immobilising your opponent or by pushing or thowing them off of the platform. There is a drop-off around at least half the perimeter of the platform.
